validation of Id's too restrictive
----------------------------------
Key: MNG-3999
URL: http://jira.codehaus.org/browse/MNG-3999
Project: Maven 2
Issue Type: Improvement
Components: POM
Environment: xp, SAP NetWeaver, maven 2.x
Reporter: Sven Pressler
Attachments: pom.xml
I guess the validation of the Id's were introduced after issue MNG-801.
I think the validation is too strong.
The problem is that a lot of valid filenames are not validated as true.
The problem is caused by the DefaultModelValidator: private static final String
ID_REGEX = "[A-Za-z0-9_\\-.]+";
This regular expression is far too restrictive since something like
"x=+%$ยง~!#^.jar" would be a valid filename on a windows operating system
I stumbled upon this because I'm developing tools for SAP NetWeaver, currently
we still use maven 1 to build our projects but we're in the process of
upgrading to maven 2.
maven 1 doesn't have this problem, since Id's didn't get validated like that.
Problem is SAP have a lot of libraries that have '~' in their names, like
'tc~epbc~pcm~adminapi~java-5.x.y.jar'. Doesn't look any good, I don't like it,
I didn't make it like that but I have to work with it.
Maybe someone can explain why it's a good idea to be that restrictive about the
Ids, but as far as I see it, it's more like: before MNG-801 there was no
validation, and after MNG-801 there was some validation, and until now, there
was not too much complaining about it.
Attached is a pom which produces the following when trying to run mvn install:
Project ID: group:com~company~my~project
Validation Messages:
[0] 'artifactId' with value 'com~company~my~project' does not match a
valid id pattern.
Reason: Failed to validate POM for project group:com~company~my~project at
